There are many different certificates. These are older and we can discuss the recent certificates when you call.  I am very discreet due to all the pirating that goes on with the web. Heart certifications are done by a cardiologist.  I believe mine is one of the top in the country. 

The latest heart certifications were done May 6, 2010.  The latest Hip and Elbow are scheduled October 5th 2010.  I keep them updated and you get copies at time of delivery.  

My Sire Charlie has been OFA Heart, Bone and Patella Certified.  By the way, Rainey will be 11 this year and he is still OFA Heart Certified.  Amazing!!!
